Database layer: SQL vs NoSQL (Mongodb specific)

Overview
I would like to discuss why we use PostgreSQL and Knex.js instead of MongoDB and Mongoose

In my opinion, I think that choosing MongoDB has more advantages than SQL.
That is why i want to have a strong discussion where we mark all the advantages and disadvantages of each system.

There is also an article in the links that gives a pretty good comparison (but is very mongoDB opinion based).

interesting quote from the article:

Working with data as flexible JSON documents, rather than as rigid rows and columns, is proven to help developers move faster. It’s not hard to find teams who have been able to accelerate development cycles by 4-or-5x after moving to MongoDB from relational databases. Why is this?:

Amazon S3 Proxies

Describe what you'd like to discuss
Amazon S3 uploads

Additional context
The first weeks of a project I'm currently doing were all about creating a file upload proxy that pipes files to Amazon S3. A lot of online sources & courses recommend using multipart which results in first caching the file on your server before creating a new stream from your proxy server to S3. I've integrated with S3 multiple times and have always thought that the simple multer implementation is a huge bottleneck. In this file service I took a different approach which I believe to be better. I'd like to show & discuss this alternative implementation during the gathering

Additional context

A first test could be that we integrate with the icapps google domain so that internal users can be authenticated
